Me and my friends made up a game we named "base warfare"
Rules and description:
Find an area to play airsoft out doors. Built two different forts within view if each other (not to close though)
Split everyone up inti two teams and make them fair based on weapons and experience.
Each team starts in one of the forts you've made
Once the game starts each team faces each other head on, no flanking if any kind you just push entail you take the other teams base
You respawn after 2 minutes at your base/fort
Whoever controls both forts wins

This game is extremely simple but if everyone had AEG and CQB weapons it's unbelievably fun and plus you can't loose the game cuz your opponent can't flank you, it ends up being whoever had the most gun skills wins

VIP assassination
U start by getting 1 to 3 sniper teams (1 sniper and 1 spotter) and put everyone else on another team. Now get a balloon and tie it to a chair. The snipers have to shoot this ballon without getting shot themselves. The defenders can build all the defenses they want but there has to be a clear shot to the target at all times. If a defender is hit he doesn't yell out. He puts his weapon above his head and exits silently since stealth is the name of the game. If all snipers are hit or a certain amount of time runs out. The defenders win. Also if a sniper is down the spotter can take his gun and start sniping. This is a long but fun game. It gets very fun when u have lots of ppl. Try this at ur next event

Sniper tag. 6 people. 4 methods play in an open field surrounded by woodland. Hunted start in middle, hunters start in woodland

1: 5 people hunt 1 person. It's good to be the 1. Person who gets the 1 becomes the 1. 1 shoots anyone and they're immobilized for 1 minute.

2: other way around, zombie style instead of immobilization

3: 1 person hunts 5 people. Each try to expose others by shooting next to them or throwing smokes or bangs at them. If a hunted shoots another hunted, the shooting hunted is out. Last hunted out wins. Hunted can immobilize for 30 seconds.

How about everyone gets handed a card it says assasin protector or prez an odd number of people 1 on the prez team and then divide the other teams evenly assasins can go with the protectors to add confusion the rest of the assasins can be snipers or guerrillas no spawning if assasins kill prez assasins win if protectors kill all of the assasins protectors win

Manhunt: Everbody at the field picks up their AEGs and points them at a select person. Yell "Run" and hunt them...... J/K!! (but we really did that once and the kid that was hunted came out a bloody mess.) my friends and i were only amateurs and noobs then, so dont flame. Im much more mature now.

Territory wars
Basically you get some flags, and place them in the woods in unique spots such as a creek, a big tree, and a huge rock. The team that captures all 3 points first by warding off enemies wins.
